Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Formula for slope: (y2-y1)/(x2-x1)
Plug the numbers in: (-10-(-20))/(-7-(-8))=10/1=10
Slope is 10.
6 minutes
because 60 divided by 10 = 6
6 = 1\10

Answer:
341,25
Step-by-step explanation:
W = HR + 1,5VR + B + T
H = 40
R = 5
V = 45.5 - 40 = 5.5
B = 0
T = 100
W = 40×5 + 1.5×5.5×5 + 0 + 100
W = 200 + 41,25 + 100
W = 341,25
